My model doesn't set up for texture painting properly
Here is a simple way to do that:


List item
Select your object
Go to Edit mode ( Tab key) 
Go to UV Editing ( see bottom of the application) 
Move the mouse under your object, press U key, and select Smart UV Project.
You can use Mark Seam / Mark Sharp ( Ctrl+E) to fix your UV map.


This will make your texture based on the UV map.
This texture is your cloth material (with UV).

When you are painting your texture you will paint on this texture.
